UHMWPE Floating Dredge Pipe Advantages:
1, High efficiency: UHMWPE pipeline has a very low coefficient of friction and is self-lubricating, the roughness of the UHMWPE pipeline is 0.00022, while the HDPE pipeline is 0.01 and steel pipeline is 0.1. The smooth interior surfaces assure low friction loss and high flow rate. Therefore, the flow capacity of UHMWPE pipes is more than steel pipes. Under same flow rate, the UHMWPE pipes could save 20% fuel for the dredgers.
2, Wear resistant: Higher Wear Resistance: Of all the pipe materials, UHMWPE pipes exhibit the smallest abrasion index. Of all the plastic pipes presently available, the anti-abrasion performance of UHMWPE is4 times of HDPE pipeline, 18 times higher than phenolic polymers, 6 times higher than polyamide polymers (PA66), 5 times higher than poly(tetrafluoroethylene) (PTFE) as well as being 6.6 times higher than carbon steel, 5.5 times higher than stainless steel and 27 times higher than copper, so UHMWPE pipes can profoundly increase the service lifespan of slurry pipes.
3, Anti corrosion: The UHMWPE pipeline with very stable chemical property, it is strong acid, strong base and so on.
4, Anti impact: The impact resistance of UHMWPE pipes is 2 times of PC, and 10 times of PTFE. With good impact resistance, which could withstand the great water hammer impacts from various sand, muds and slurries.
The UHMWPE pipes are continually extruded by special extruders and moulds. Here is the brief introduction of
UHMWPE pipe production:
1. The UHMWPE powder will be melted together with a small amount of paraffin, carbon black in high temperature
2. Different pipes with different diameter and wall thickness will need to make different moulds.
3. the length of the UHMWPE pipes could be cut according to customers requirements
4. The color of UHMWPE pipes is the original color of the raw material, and it is specially processed during production.

I. UHMWPE VS. HDPE Material
II. Performance Comparisions between UHMWPE pipes&HDPE pipes
1. Good Wear Resistance enables the UHMWPE pipes to have longer service life
Based on the sand and slurry testing,UHMWPE has an abrasion resistance 4.4 times higher than HDPE.
2. Less Maintenance Time and Costs, Less Downtime,Less Loss of Production
The far superior wear resistance of UHMWPE pipes will significantly increase the time between pipe replacements and rolling
which can significantly:
1) Reduce maintenance costs and time
2) reduce downtime for maintenance and less loss of plant production line
3. Reduced Pumping Costs
With a surface roughness of 0.00022mm while HDPE is 0.01mm, UHMWPE pipe is extremely smooth, which means less friction, less pressure loss and 20% energy inputs will be reduced to deliver the same result:
